With Antialias enabled some PDFs show rendering artifacts. Please see the attached pictures for a comparison (the picture are from okular).
The artifacts go away if the option is disabled (however that means poor general rendering quality).
Readers not based on poppler are not affected (e.g. mupdf).
The problem is in the slight darker outline that can be seen at the end of the blurred region. It should be easy to spot the problem if you open the test pdf in okular first and then with mupdf
